<h1>Incompatibilities between Eclipse 4.21 and 4.22</h1>

<p>
  Eclipse changed in incompatible ways between 4.21 and 4.22 in ways that affect
  plug-ins. The following entries describe the areas that changed and provide
  instructions for migrating 4.21 plug-ins to 4.22. Note that you only need to look
  here if you are experiencing problems running your 4.21 plug-in on 4.22.

<p><strong>What is affected:</strong> Clients that use <code>Servlet</code> APIs coming with Eclipse Platform.
</p>
<p><strong>Description:</strong></p>
Eclipse has updated to ship Servlet API to version 4 from previous version 3.
<p>
Bundle <code>javax.servlet</code> is renamed to <code>jakarta.servlet-api</code> to reflect the Servlet API being developed by JakartaEE project now. <br>
Version 4.0 still keeps the <code>javax.servlet</code> package names as change to <code>jakarta.servlet</code> package names is not yet adopted by Eclipse.
</p>
<p><strong>Action required:</strong></p>
<ol>
	<li>Adjust build scripts, target platform and etc. to use the new bundle symbolic name. </li>
	<li>Implement and adjust to new Servlet 4.0 APIs</li>
